Gtf2b | Transcription initiation factor IIB; General transcription factor that plays a role in transcription initiation by RNA polymerase II (Pol II). Involved in the pre-initiation complex (PIC) formation and Pol II recruitment at promoter DNA. Together with the TATA box-bound TBP forms the core initiation complex and provides a bridge between TBP and the Pol II- TFIIF complex. Released from the PIC early following the onset of transcription during the initiation and elongation transition and reassociates with TBP during the next transcription cycle. Associates with chromatin to core promoter [...] (316 aa) | ||||
Cdc25c | M-phase inducer phosphatase 3; Functions as a dosage-dependent inducer in mitotic control. Tyrosine protein phosphatase required for progression of the cell cycle. Directly dephosphorylates CDK1 and activates its kinase activity. When phosphorylated, highly effective in activating G2 cells into prophase (By similarity). May be involved in regulating the proliferation of T-lymphocytes following cytokine stimulation. (447 aa) |
